Benefits of technology

[0011]More specifically, a further aspect of the present invention is a cooking gas hob provided with a grate presenting some characteristics capable to solve the problem of the flame extinguishing due to wind blows and which also doesn't need to change the disposition of the fingers, compromising the stability of the cooking utensils supported by the grates.

Problems solved by technology

This change has decreases the performance of the product when using the same burner at the minimum level.
This effect is particularly undesirable when the burner is used for simmering, especially when needed to supply good melting and good sauce results.
In fact, a burner with increased power is not good enough for this purpose.
As a consequence the overall grate ornamental design is changed, and this change can compromise the overall stability of the cooking utensils and jeopardize the overall aesthetic design.

Embodiment Construction

[0015]With reference to the drawings a gas hob 100 presents five burners having different sizes, adapted for being coupled with different pans and for supply different powers. In particular the gas hob presents an auxiliary burner A having a small size, i.e. rated 1.5 kW and rapid burner R rated, for instance, 4.4 kW. Three grates G are positioned above the burners, each of them presenting “fingers” F to support cooking utensils (cookware) of different sizes.

[0016]According to the present invention, the grate G above the auxiliary burner A, which is the burner that first extinguishes it flame when set at its lower (minimum) power level during the door slam test, present a flat surface metal area M, a plate, which avoids the flame be directly in contact with the pan at low power level, and which prevent an excessive warming when the customer is using the burner of the product on the simmer function.

[0017]The same configuration is applicable also to the grates over standing the rapid ...

Abstract

Gas burner assemblies include a cooking gas hob and a grate for supporting cooking utensils. The grate includes a plate which integrates a protection for preventing the flame of a burner from being extinguished from a wind blow when operating around the minimum level. Simmering performance of such burner assembly is enhanced.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Gas burner assemblies include gas hobs and grates are associated with a gas built-in cook top or a gas cook top integrated within a cooking range. For the purpose of the present invention we extend this definition by including all the cooking gas hobs provides with at least one burner fed with any type of combustible gas.[0003]2. Description of the Related Art[0004]Burner assemblies include gas hobs having gas burners with grates placed above the gas burners. Grates normally present “fingers” for supporting pots, pans, casseroles or any other cooking utensil that has to be heated by the gas hob.[0005]“Fingers” are required to position, in a centered and stable way, cooking utensils above the gas burners.[0006]Generally, gas hob appliances are designed to prevent the flame from being extinguished by a wind blow caused for instance by a slammed door, especially with regard to the low power burners. This design is particul...
